The bike runs great but it seemed like the stock clutch was slipping, so I replaced the plates with the Barnett 'extra plate' kit, and a new Barnett performance spring kit. I'm running ATF in the primary case.
After 300 miles or so, I've noticed two things. One, finding neutral is a pain, and two, the clutch doesn't complete disengage when activated. I've adjusted the cable to specs (as per the manual) and the done the same with the clutch itself. I'm not sure how to deal with the drag. It feels minor, because when I'm stopped, but in first gear with the clutch pulled in, I can keep the bike from moving just with my feet on the ground. But the bike wants to move.
Has anyone dealt with anything like this? As always, any advice is very much appreciated. Thanks!!

I would flush the ATF out of the primary and just put 20-50 dino oil in it. I use synthetics everywhere else but the primary. There I use the cheapest oil I can with no friction modifiers and let the clutch do what it was designed to do.

I've followed the install guide and everything went in just fine. I like the idea of dumping the atf and going with a 20-50 non-synthetic. In the install instructions that came with the clutch pack, Barnett noted that several folks had reported problems using Formula +. Thanks for the help I'll let you know how it works out

Thanks all for the insight. I prefer to do the work myself rather than taking it to the dealer. Not that I mind the dealer making a buck mind you, just not 120 bucks an hour for a job that should take 30 min and is pretty straight forward.

I'm not sure the cable is an issue as I still have some adjustment left in it, but it COULD be the problem. It's the original cable and now has the added spring strength. I'll see what I can do as far as adjustment goes, both clutch and cable.

I'm a little concerned about the atf in hot weather. Any other thoughts on that?

Barnett my recommend ATF but I guess i'm a little old fashioned and think ATF is good in automatic trannys but not so much in a clutch setup. JMHO.
Take a look in the primary oil poll and see what others are using and why.
